چکیده انگلیسی
We present a model for the steady-state (or equilibrium) behaviors of the voltage-gated ion channels in cell membranes using the non-extensive or generalized statistical mechanics. The equilibrium value function in the gating kinetics of batrachotoxin-modified sodium channels from a squid optic nerve in planar bilayers are calculated for different values of entropic index (q) which characterizes the degree of non-extensivity of Tsallis' entropy and the fractal structure of the channels. It is found that in the limit qâ1, the results of calculation reduce to the results described by the well-known Boltzmann statistics or the extensive physics. For the non-extensive case (qâ 1), a small deviation with respect to the Boltzmann curve which was observed in a great variety of physical systems occurred.
